ABSTRACT: The Microbial Fuel Cell (MFC) is a bioelectrical system
that can convert chemical energy into electrical energy. The anode plays
an important role in the improvement
of power generation. Zeolite and carbon-based materials were coated in graphene
felt anode in this study for proof of concept that the modified material could enhance power generation.
Preliminary results showed that the
maximum power density with the modified material was 2 - 2.5 times higher than the unmodified material using RAS as a
substrate and 1.4 times higher using algae as
a substrate in our single chamber model, whereas the dual-chamber model displayed a maximum power density
of the modified material to be roughly 3 - 4 times
higher than in the unmodified microbial fuel cell.
